Short of pulling it apart and cleaning it, try some TV tuner contact spray cleaner. Sometimes that works. An electronic grade degreaser may work too. They are available in most electronic supply stores and online.
thanks phil
Just make double sure the tuner cleaner or degreaser are plastic safe. Most are, but it is a must around wire insulation, motor windings etc

ok
If the spray treatment doesn't work, you will have to disassemble the E unit and demagnetize the plunger.
train doctor how do you demagnetize the plunger?
Others have different ideas, but I disassemble the reverse unit, take the plunger out, put the part of the plunger that goes into the coil on an anvil, and give it a couple hearty taps with a hammer. Afterwards, smooth out the part you hit with a Scotchbrite or emery cloth. Clean it well with alcohol or CRC Electramotive. Mae sure that the slot the plunger's cross piece slides up and down is clean, as well as the area where the drum turns is clean. Clean the fingers where they contact the drum, check the drum to make sure that the pivot that goes into sides of the reverse unit are in good shape, and clean the contact area on the drum while you have it apart. If this is your first, take pictures with your phone or digital camera, to have a reference. You can tell people that have done this frequently by their addiction to scotch and their white hair.
The greatest demagnetizer ever made for small parts is called a souldering gun. Turn the gun on and slide the item in and out from between the large wire that makes the souldering tip. Be sure to keepthe gun turned on until you have removed the item from the tip area or you may remagnitize it again.
